Comment 33 for bug 1621798

I found out that i did not comment on this bug.

Here is what debugging showed.

`RolesNegativeTestJSON:test_delete_role_by_unauthorized_user` fetches a token;
`RolesNegativeTestJSON:test_delete_role_request_without_token` deletes this token;
`RolesNegativeTestJSON:test_list_roles_request_without_token` tries to delete this token again.

3 different tests try to operate with the same token. Debug output shows that this token came from keystone only once. So, tempest for some reason attempts to reuse the token multiple times.

http://paste.openstack.org/show/584887/ -- here is this part. It is very
verbose, expect to spend some time there. Token starts with

The bugreport should also be marked as not affecting production.
